Perhaps this will jog a memory from the past. Actor, Peter Graves, pulls out his mini tape recorder. The voice on the tape says, "Good morning Mr. Phelps, ... your mission, should you choose to accept it..." (tape destructs), (cue music).
Well, Paul Ayres does it again; and this time he really puts the organist to the test with 42 registration changes within a five minute perpetual motion piece. I could not have recorded this without the aid of my partner, Dan, who pressed half of the pistons. To do it all by oneself, (you can tell I have given it some thought) one would have to create a MIDI mouth piece which one could bite down on to advance the "next" pistons. A horse's bridle and bit come to mind. Regardless of the technical issues, it is quite a romp!
